10. GENERAL SPECIFICATIONS
HART
Communication Distance;
Up to 1.5 km (1 mile) when using multiple twisted
pair cables. Communication distance varies
depending on type of cable used.
Use the following formula to determine cable
length for specific applications:
L= -
65 x 10 6
(R x C)
(C
f
+ 10,000)
C
Where:
L = length in meters or feet
R = resistance in Ω (including barrier resistance)
C = cable capacitance in pF/m or pF/ft
C
f
= maximum shunt capacitance of receiving
devices in pF/m or pF/ft
